NVD Description

Note: Versions mentioned in the description apply only to the upstream perf6.12 package and not the perf6.12 package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

bonding: alb: fix uninitialized transport header access in alb_determine_nd()

alb_determine_nd() uses icmp6_hdr(skb) to inspect ICMPv6 headers. However, in xmit paths (e.g. packets sent via AF_PACKET / raw sockets or forwarded packets), skb->transport_header is not guaranteed to be initialized. While pskb_network_may_pull() ensures the packet data is linear starting from the network header, it does not set or adjust the transport header offset.

Dereferencing icmp6_hdr(skb) can therefore access out-of-bounds memory.

Fetch the icmp6hdr directly after ipv6hdr following pskb_network_may_pull(), and reload ipv6hdr in case pskb_may_pull() reallocated skb->head. Also remove the unused bond argument from alb_determine_nd().
